The holder consists of a marginal frame 2, preferably formed of stiff Wire and of the desired shape,-as for instance, square. Crossing/the frame 2 are a series of longitudinal Wires 3, and another series of transverse wires 4. These Wires cross each other as represented, but are spaced apart at their intersections sufiiciently to permit the sheet C to the slipped between the Wires, for instance, overlying the longitudinal Wires 3 and underlying the transverse Wires 4, as best represented in Fig; 3. 5, 5 indicate a pair of fingers extending i serving to retain t 11 23. ispa ;masse 1 diae a llap a was a ros hehame rpm the corners at one en thereof. iThe nds l e,se .fiaee are.an u n dc saadic t d e e g e t i s 00. tit-meshes the ed; f he a ee held r ay l ani liedwas y gui i reat s was a r W n el q wtl i t ens awb ch ar nail he desgrihe ql'.

use a single spring, as represented in Figs.

1 to 3, as that is more satisfactory in use.

In using my invention a color sheet C of suitable material, as for instance, thin transparent celluloid, is slipped between. the cross Wires 3 and 4. of the frame. then applied to the lamp, as represented in Fig. 1. The edge of the shade is first caused to rest against the stops formed by the 1113- turned ends 6 of. the fingers 5, and then the free, intermediate, elastic, portions 10 of The latter is the spring is stretched until it is caused to spring over the edge of the shade. In stretching the spring over the edge of the shade the portions 11 will be more-or less expanded or stretched according to the size of the shade.

The spring forms a resilient attaching means that will hold the frame securely and is easily manipulated whenever the frame is to beapplie'd to or removed from a lamp shade.

My invention is primarily intended as a holder for sheets adapted to be used in connection with lamps for securing colored illumination effects, but it is apparent that it is equally adapted to holding other objects than transparent color sheets, and that the holding frame is adapted to be applied to the edge of other articlesthan lamp shades, andhence I wish it tobe understood that my invention is adapted for other uses than the single one in connection with which it isherein specifically described.

.What I claim is: 1

1. A holder for a flat sheet, comprising a frame in which the sheetis held, adapted to cover the open end of a [shade for a lamp,

' and an elastic attaching means for detachably uniting the holder to the shade, the ends of which are secured to the holder at the opposite sides thereof, and its intermediate portion being free and arranged to be sprung over and encircle toa certain extent the peripheral edge portion of the shade. A

2. Aholder for a sheet'of material, consisting of aframe, an extensible springsecuring means extending across the frame and connected therewith near the opposite edges thereof, and fixed stops, the'stops being arranged to engage with the edge of a .lamp'shade and the said cross securing means being arranged to be sprung over the edge of the shade'oppos te that portion which engages the said stops.-

3. A holder for a sheet of material, consisting ofa frame formed of crossed wires between which may he slipped the sheet to be held, and a spring connected With the frame near its opposite edges and extend-- ing across the frame and adapted to be sprung'over the edge of a shade to hold the frame in engagement with said shade.

4. A holder for a sheet constituting a light screen, consisting of a frame, crossed wires between which the sheet is placed, bars at the opposite edges of the frame and a,

coiled spring, the end portions of which surround the said bars and the intermediate,' extensible," portion of whlch extends across the frame and is adapted to be sprung over the edge of alamp shade.

'5. Aholder for a light screen, consisting of a flat frame having crossed wires between which the sheetconstituting the screen may be slipped, stops near'one end of the frame,

bars atthe sides of the frame, and a coiled spring, the end portions of which surround the said bars and are movable thereon as the said portions are extended, and the intermediate portion of the spring extending across the frame from one bar to the other, the frame being adapted to be applied to :1

lamp shade the edge ofiwhich engages with the said stops, while the portion of the spring extending across the frame is sprung over the'edge of the shade.
